Be it known that ll, HOWARD Van B. PALMER, a citizen ofthe United States, residing at Dumont, in the county of vBergen and btate of Newdereey, have invented certain new and useful improvements in Photographic Devices, of which the following is a full, clear, and exact description, such as will enable others smiled in the art to which it appertains to make and use the same.

rlhis invention relates to photpgraphic devices, and with respect to certain more specific features thereof, to devices of such a be used in connection with the more penetrating rays of light, such, for instance, as the X-rays. c

This invention has for one of its objects to provide apparatus of the character above referred to which will embody featuresof simplicity and durability.

Another object of this invention is the provision of a compact and inexpensive apparatus for reproducing optical phenomena in connection with the human body and to make such a reproduction upon a flexible film in contradistinction to a rigid plate.

@ther objects will be in part obvious and in part pointed out hereinafter.

rlhis invention probably finds one of its most important applications in connection with the X or Rntgen rays, but it is to be Vunderstood that it is not limited to a use employing this particular class of rays.

lt will be obvious that the invention in its broad aspect might be readily and effectively used in connection with ultra-violet rays, the effectiveness of the device in the various instances of employment of rays of different characters being dependent merely upon the respective transmitting, reflecting or absorbing properties of the materials used.

lt is to be understood further that certain broad .features of the invention areappli cable to the ordinary photographic device employing alens or a plurality of lenses.

rlhe invention accordingly consists in the features of construction, combina-tions of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in thevfol-` lowing claims.

Referring now shown one of various possible to the drawing, in which is embodiments p projecting of the inventionf-Figure 1 is a general longitudinal section of the invention, witha source of X-rays indicated in operative relation thereto; Fig. 2 is a plan view with upper parte of the casing and associated members removed to show more clearly the interior structure; and Fi s. 3 and 4 are, respectively, enlarged detail views in longitudinal and cross-section of a portion of the feeding mechanism for the film used in connection withthis invention.

lin the drawing, inwhich similar reference characters referto similar parts throughout the diner-ent views, the numeral l indicates a casing in which a lm support embodying a rotatable film-spool 2 is mounted. On this spool may be arranged a continuous supply of flexible sensitized film sufficient for taking a plurality of X-ray photographs of the object. flhe casing 1 in this preferred form of the invention is provided, on. the upper side thereof, with a substantially opaque light baille 3, preferably of lead, and providedwith an aperture or film exposure 4. Disposed across the aperture 4 is -a second light baille 5, consisting of two sheets 6 of aluminum or like material impenetrable by ordinary light and substantiallv transparent to or penetrable by the X-rays and which may wholly or partially support the object to be photographed. The casing l has a downwardly extending portion 7 for a purpose which -will hereinafter be set forth. 0n the inner side of the bottom wall 8 there are provided two series of guiding rollers 9 and 10 spaced apart and adapted to guide rack members 11 and 12 of a bail-shaped member mesh with relatively corresponding gears 14 and 15 xed to a shaft 16 and havin bearings in the casing 1, as indicated at 1 and 18. @ne end of the shaft 16 projects through the casing and is provided on its end with a handle 19 to rotate the same.

The rack members 11 and 12 are, respectively, provided with oppositely disposed slots 2() and 21 and slidably engage a cross member 22. An intensifying member or screen -23 comprising a flat-sided plate for iating the vhlm at the place of exposure is movably mounted in the casing 1, as by being p'voted at 24, and has a movement on said pivot toward and away from the exposure aperture 5 and the plane in which the exposed portion of the film lies when a The rack members 11 and 12 l .photographlis lbeing taken,

orange paper 28 or provided blade or cutter 47 secured to the lupper side of connecting and 26 pivotally connecting the lntenslfy- Y. ing screen '23 with the cross member 22.

The film 27 is wound on the film-spool 2 and vcovered throughout its winding by means of the flexi le light-filter, as the any 'suitable material. Upon a shaft 29, fixed in the casing 1 and secured therein against rotary displacement by means of a squaredend 30, there'. 1s loosely mounted a receiving roll or second spool 31. This receiving roll 31 1s provided with a flange 32 at either end thereof,

'and aV spring-pressed`plunger 33 adapted to co-act with teeth 34 formed on the inner surface of the disk 35. Disk 35 1s provided vwlth an interior coil leaf sprig 36, one end of which is secured to the d1 35 and the other to the shaft 29, as indicated at 37.- A

- flexible tape 38 extends from one end of the rack mem er 11 to the disk 35 and is fixed thereto, as indicated, at 39. Suitable glnde rollers 40 and A41 and a guide member 42 are to direct. the feed of the orange paper 28. .A resilient stop .43 is. supported by the lower wall of the casing and providesv resilient abutting means for the intensifying screen when in its lower position. An adjustable knife blade o rcutter is indicated at 44, adjustable between the thumb-screws and 46, and adapted to coact with a knife end of the lntensifying screen 23. An indicator 48 is supported by the lower wall 8 of the casing 1 and projects upwardly 'slightly above vthe the intensifying screen 23 when the latter is in its lowermost position. This indicator is adapted to be engaged by the end edge of the lm 27 and be moved thereby to advise the operator vthat the film is ready for the first exposure. It is to be understood that suitablemeans (not shown in the drawing) are provided to temporarily open a portion of the casing l for the purpose of making various necessary adjustments.. It will be observed that by the foregoing arrangement the main supply of film is effectively screened from action of the X- rays, the lead screen 3, being disposed between .the source of X-rays and the film- Assuming that the necessary preliminary adjustments have been made,

stance,

as the introductionof the ilmspoo1 into the casing and the passing` of the orange paper r. over the rollers 40 and 41 tothe second spool or receiving roll 31 and the paper to the spool-31 1n anysuitable manner,

the operation is as follows:

The shaft 16 is rotated in the. 'direction of the arrow by means of the handle' 19 and thereupon the gears 14 and 15, fixed to the shaft 16, will move the bail-shaped member 13 'in a forward direction.. As this member moves forward the flexible tape 38 is taken up upon the disk 35, the latter having a tendency to rotate in the proper direction by reason of the spring 36, it eing understood that the teeth 34 are suitably shaped to click by the springpressed plunger 33 in the take-up direction of movement. As the rack members 1l and 12 of the bail-Shaped member 13 move forward the opposite ends of the cross member 22 Vplay in the slots 20 and 21, respectively, until the rear walls of said slots take up the opposite ends of the cross member -22 and carry the same in a forward direction. This causes the intensifying screen 23 to move about its pivot 24 and the handle 19 is rotated until the intensifying screen 23 has been moved into a position parallel to the bale members 6. At this time the device is ready for the application of the light rays, it being understood that the object to be reproduced is supported upon the top of the casing between the source of light and the exposure aperture. After the exposure, the handle 19 is rotated in the opposite direction, moving the rack members 11 and 12 toward the film-spool 2. The tape 38 is thereby moved in the same direction, tending to unroll the same from the disk 35. The teeth 34 of said disk are so shaped as to provide a locking engagement with the plunger 33 in this backward direction of movement. This causes the receivm spool 31 to turn about the shaft 29 in a m feeding direction and to take up a predetermined amount ofthe orange paper 28. The orange paper 28 being wound with the film 27 and thus operativelypconnected to the liln-spool, it will be obvious that this movement of the one will cause a corresponding movement of the other, and as the orange paper 28 is taken up upon the receiving roll 31, the lilm 27 is simultaneously'moved ver the intensifying screen 23 and down into the closure 7, a successive portion of the film being thus moved to position opposite the object support, and then into position opposite the impervious screen. `It will furthermore be noted that the construction of the apparatus is such that when .photographs are being taken, ordinary light is excluded from the interior of the casin at any part where the film might be fogge .It is observed that in ca a strong support for the object being hographed is not required, the orange paper 28 alone would be sufficient to support a light object, and at the same time protect the film' from ordinary light.

As the rack members 1l and 12 move toward the film spool 2 the cross member 22 lltll intatta follows the retreating end walls of the slots 20 and 21 because of the substantially heavy character of the intensifying plate or screen which drops by gravity until checked by the resilientstop 43. Further movement of the rack members 11 and 12 causes the opposite end walls of the slots 2O and 21 to contact with the crossv member 22 thereby positively engaging the plate or screen 23 with said stolp.v -he above-described operation presents the film for exposure and subsequently moves the lm out of the plane of exposure and yfeeds it in a general direction toward the downwardly extending .portion 7 of the casing 1. Upon the next movement of the rack members 11 and 12 forward and a consequent movement of the intensifying screen 23 carrying the knife blade 47, the previously exposed portion of the film 28 will be severed froni'the remainder of the film by reason of the cutting engagement of the knife 47 on the movable intensifying screen 28 with the fixed knife 44 and the exposed portion of the film will be disposed in the portion 7 of the casing 1, where it may be immediately developed or where it may be merely temporarily retained. A retard 50 is provided bearing against the film-spool 2 to prevent over-running of the film.

it will be seen from the above description that there is provided an extremely simple and compact device comprising a' flexible film and one which is adapted to be used in connection with the X-rays or with the other more penetrating rays. v

For convenience the term X-ray will be used in the following claims although it is to be understood that this is a mere relative or descriptive term to describe those rays of light of a more penetrating character than ordinary light rays and for this reason is not to be interpreted or limited to that specific type of rays technically known by this name.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
